What is iron ore raw material?
Raw Materials Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less. Coke is a substance made by heating coal until it becomes almost pure carbon.
What are the 3 main raw materials in the production of iron & steel?
There are three main raw materials needed to make steel. Iron ore, coal and scrap steel.
What are the types of iron ore?
Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.
What does raw iron ore look like?
Iron Ore. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. 98% of the mined iron ore is used to make steel.
Which is the main raw material of iron and steel industry?
iron ore
The basic raw materials that are used in the iron and steel industry are iron ore, coal, limestone, manganese, silica and feldspar.
What is the raw material of iron and steel company?
The ores used in making iron and steel are iron oxides, which are compounds of iron and oxygen. The major iron oxide ores are hematite, which is the most plentiful, limonite, also called brown ore, taconite, and magnetite, a black ore.
What is the best iron ore?
Magnetite
Magnetite. Magnetite is the finest ore among all the ores of Iron. Magnetite ore comprises of seventy per cent of iron. The magnetic properties in this ore are appreciable.

What is iron ore?
Iron ore is one of the basic among other raw materials used in the production of iron. It is described as any mineral substance that contains enough iron which makes its smelting a viable proposition, i.e an iron content of less than 20%.
What are the basic raw materials for making iron and steel?
The basic raw materials for making iron and steel are: Iron ore is one of the basic among other raw materials used in the production of iron. It is described as any mineral substance that contains enough iron which makes its smelting a viable proposition, i.e an iron content of less than 20%.
What is iron oxide?
Iron is found as a chemical compound (usually an oxide) within the ore. These ores are generally smelted containing iron oxide materials like magnetite, hematite, and limonite. Magnetite ores are the richest known with around 65% of iron. It is a ferrosoferric oxide (Fe3o4); That is, black, dense, and strongly magnetic.
How is iron ore converted into high-quality steel?
Iron ore is converted by reduction in the blast furnace to high-quality hot metal, a product which serves as the basis for all steelmaking processes. The criteria for the purchase and processing of iron ore are the iron and acid content, among other important properties.
